摘　　要：基于Multisim 10.1对蔡氏电路的功耗进行仿真研究。区别于以往分析混沌演化的时域、频域和相图特征方法,本文着重研究蔡氏电路的混沌复杂性与功耗的关系。首先调整蔡氏电路的电感,测量和分析纯阻的耗散功率特征,然后调整电阻(R=1)验证由电感变化(L=0.1mH)引起的功耗变化(P≈0.26mW)。最后得出,向蔡氏电路(Vcc≡±5V)注入大于0.26mW的功率,可以实现混沌从双涡卷状Chua吸引子向极限环的演进。The simulation of power consumption of Chua＇s circuit is addressed on tool of Multisim 10.1. Differing from previous study to Chaos, such as time domain, frequency domain and phase diagram, this paper focuses on the relation between complexity of Chaos and power consumption in Chua＇s circuit. It firstly adjusts an inductance in Chua＇s circuit to investigate the power consumption character, and then, changes a resistance （△R=1Ω） to validate the power consumption variety （△L=0.26mW） induced by the inductance dispersion （△L=0. lmH）, at last concludes that the power consumption which is more than 0.26mW injected in Chua＇s circuit can realize Chaos＇ evolution from Chua double scroll into limit cycle.
